YourMemory — Persistent Memory for AI Agents | MCP Compatible
MCP COMPATIBLE89.4% RECALL@5
Your AI should remember you.
YourMemory gives any AI assistant persistent, intelligent memory across sessions — with biologically-inspired decay that forgets the right things at the right time. Open source. Runs entirely on your machine.
Three steps. Your AI agent learns, remembers, and naturally forgets what it no longer needs.

// THE ENGINE[ 02 / 07 ]
Three layers. One engine.
Vector search finds what you asked for. The graph finds what you forgot to ask for. Ebbinghaus decides what survives.

// MEMORY DECAY[ 03 / 07 ]
Watch memory fade.
Every memory carries a strength score S(t) = e−λt. Different categories age at different rates. Drag the half-life — when strength drops below the prune line, the memory fades from retrieval.

// BENCHMARKS[ 04 / 07 ]

// YOUR NUMBERS
How much would you save?
Two ways to see your numbers — pick whichever fits.
1
Instant audit — runs entirely in your AI session
Copy this prompt and paste it at the end of any Claude, ChatGPT, or Cursor session. Your AI will reply with the exact token breakdown and a compressed memory block — no need to paste anything back here.
{{ auditPrompt }}
Your AI will respond with: Full session: ~X,XXX tokens · YourMemory would store: ~XXX tokens · Savings: XX%
or calculate from your full history
2
Deep dive — paste your full conversation history
Export or copy your full session transcript and paste it below. We tokenize it locally and show you the cumulative cost across sessions.

Paste your full conversation history, set sessions & model, then click Calculate savings.

Context grows each session — by session {{ calcSessions }}, you're re-sending {{ calcCtxPerSessFmt }} tokens of history every time.

~{{ calcYmPerSessFmt }} recalled tokens injected per session — flat, never growing.
Vector stores hoard chunks and never forget. YourMemory keeps memory that strengthens, fades, and connects — like yours.
Legacy · vector DB
Stores chunks. Returns chunks. Each session starts from zero — and nothing is ever prioritized or forgotten.

YourMemory
Facts that evolve. Knowledge that merges, decays, and connects across every session — so only what matters survives.

// ENTERPRISE[ 06 / 07 ]
Memory across your whole team.
Your team accumulates deep knowledge every day — customer quirks, solved problems, architectural decisions. Right now it evaporates when the session closes. Enterprise gives it a permanent home.

Engineer A spends 2 hours debugging a customer's edge case. Session closes. Knowledge gone. Engineer B picks up the same customer next week — and starts from scratch.
